STOVEPlPE-LOCK.

SPECIFICATION forming part of Letters Patent No. 679,690, dated July 30, 1901.

Application filed March 9, 1900. Serial No. 8,057. (No model.)

To aZZ whom it may concern.-

Be it known that I, ELLIS J. STANLEY, a citizen of the United States, residing at Lanark, in the county of Carroll and State of Illinois, have invented a new and useful Stovepipe-Lock, of which the following is a specification.

This invention relates to improvements in Stovepipe-locks; and one object is to provide a simple device of this character that will effectually lock the end of the pipe to the chimney and that will also provide a stop to prevent the end of the pipe being accidentally pushed too far into the flue.

A further object is to provide, in connection with the aforesaid devices, means for securely locking the several sections of a stovepipe together, whereby the whole pipe is securely fastened in place and is not liable to be accidentally displaced.

A further object is to so construct these several locking means that they are adjusta'ble, whereby they may be easily and quickly applied to different-sized pipes and chimneys.

For a complete understanding of the invention the preferred form is fully described in the following specification and shown in the accompanying drawings, which form a part thereof, and in which- Figure 1 is a perspective view of a stovepipe and chimney broken away and showing the invention applied thereto. Fig. 2 is an enlarged perspective view of a portion of the chimney and stovepipe looking in an opposite direction from that shown in Fig. 1. Fig. 3 is a vertical cross-section more clearly showing the construction of the clamp. Fig. 4 is a vertical cross-section showing a slightlymodified form of clamp.

Similar numerals of reference designate like and corresponding parts in the several figures of the drawings.

Inthe drawings the numeral 10 designates the ordinary cylindrical Stovepipe, and 11 the fine of the chimney with which it is connected. To look the end of the stovepipe in place, two parallel rods 12 and 13 are provided, which extend longitudinally along the inside of the pipe and are, as shown, preferablyconstructed of heavy wire. One of the rods 12 has its end bent at right angles to form a retaining-hook 14, which is adapted to engage over the inner edge of the flue-opening. The inner end of the rod 12 is bent at right angles to the main portion, as at 15, and adapted to lie against the inner face of the pipe, whereby the retaining-hook 14 is held in proper position. The other rod 13 extends directly across the chimney-flue and has its end bent at right angles, as at 16, said bent portion being adapted to abut against the inner face of the line opposite the opening, forming a stop.

To secure the retaining-rod 12 and the stoprod 13 to the stovepipc, the clamp 17 is provided, which passes through an openingin the pipe 10 and securely clamps the rods 12 and 13 thereto. The preferred construction of this clamp, as shown in Fig. 3, comprises a screw threaded shank 18, which passes through the opening in the pipe and has upon its outer or exposed end the rigidly-attached thumb-piece l9. Screwed upon the inner end of the shank is the clamping-nut 20, which is provided with notches 21, arranged on opposite sides of the shank. A washer 22 is placed between the adjacent portions of the thumbpiece and the pipe. The shank 18 passes between the rods 12 and 13, which engage in the notches 21, and by screwing the clamp tightly down upon the rods it will be evident that they will be tightly clamped to the pipe.

In the modification shown in Fig. 4: a pair of oppositely-disposed clamp-arms 20 are rigidly attached to the screw-threaded shank 18, the thumb-nut 19 screwing upon the shank. The result is exactly the same, however, as that shown in Fig. 3.

For the purpose of rigidly attaching the several sections of the pipe together one of the rods is extended longitudinally along the pipe and is clamped by the devices before described at suitable distances apart. In Fig. 1 the stop-rod 13 is shown extended to the stove and clamped at the elbow and at the end length to the stove-collar; but it will be understood that the rod may not extend as far and that a greater or less number of clamps may be used, as desired.

In placing the pipe in position the rods are adjusted, with the retaining-hook of the rod 12 engaging over theedge of the flue-opening and the projecting end of the stop-rod abutting against the opposite flue-wall. The

nut 20 is then screwed down, which will clamp the end of the stovepipe and prevent any longitudinal movement. The remaining sections are then adjusted and the-rod clamped, so that there is no chance of the pipe being pulled apart.

The construction affords a simple and efficient means for securely locking a stovepipe in place and prevents its being pulled from the flue-opening or accidentally pushed too far in. It will furthermore be seen that it is easily adjustable to different-sized chimneys and that it provides means for locking the different pipe-sections together, so that the whole pipe is secured to the chimney and there is no chance of its accidental displacement.

The two rods 12 and 13 form a connection between the stove and chimney which not only serves to lock the terminal sections of the stovepipe to the chimney and stove, but also to look all of the Stovepipe-sections together and prevent their becoming disjointed.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the ad vantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with a sectional stovepipe, of means associated therewith for looking the sections together and at the sarne time securing the terminal sections to the stove and chimney, said means comprising two rods, one longer than the other, arranged within the pipe, the short rod having a retaininghook engaging the inner wall of the flue-opening, and the long rod having its end extended across the flue-opening and bearing against the outer wall, the two rods being arranged side by side within the first section of the pipe next the flue, a single clamping-head engaging both rods, exteriorly-located operating means connecting with the clamping head to clamp the rods between the head and the inner face of the first pipe-section, the long rod being extended beyond the first section and through the intermediate sections down to the terminal pipesection which connects with the collar of the stove, and means for detachably connecting the end'of the long rod to the stove-collar, for the purpose substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

ELLIS J. STANLEY.
